Today Adobe staff posted in the Adobe forum that they are working on support the DP2x sensors.

"The Merrill models use a special sensor technology called Foveon which requires very different image processing logic compared to the so-called Bayer sensors used by almost all of the other cameras. We actually are working on support for these Foveon sensors (includes all the Merrill models) but it will take some time.2

What I admire about your work is your ability to create a large DR with good detail in the highs and low and nice black. I have tried to mimic your pp without achieving your level of success. Hopfully at some point I will discover your secret.
